I have indeed heard about FreeHAL. It won "Most Popular" (in the past) in the same contest in which my bot most recently was awarded "Best New Bot". FreeHAL is now discontinued, last I've heard.
Though were did you hear that it's creator was 13-years-old during itself inception? I'm not doubting it, I just haven't found any online sources to validate that point.
I am very indebted to my parents due to the way that I was raised and the freedom which being home-schooled permitted, but my parents are not familiar with the field of computer science and I must admit that I am entirely self-taught.

As I've replied to other people: No AIML. My bot uses its own markup language custom-made to its needs that I call ACUMANSCRIPT. What makes it special is the backend, which is much more flexible and advanced then AIML (which focusing on exact string matching).
In fact, ACUMAN beat the ALICE bot in the last Chatterbox Challenge by over 20 points, winning the "Best New Bot" prize.
The model behind my project is not designed after human interaction, but rather a combination of what is the most efficient for me to maintain and best mimics human behavior.
